Plara (Isan people call it pla daek) is the savory heart of Isan cooking. Som tam, larb, koi, chili dips — almost every dish leans on plara for that deep umami punch. Kalasin takes plara so seriously that it has become one of the country's biggest producers of bottled fish-sauce concentrate, with everything from FDA-certified factories to small community makers who ferment and sell at the markets. Jaew bong, meanwhile, is a plara chili dip pounded with chilies, shallots, garlic, galangal and lemongrass into something bold and fragrant with herbs — a dish meant to be eaten with fresh vegetables that nearly every household in Kalasin keeps on hand. We pulled this together from real producers and shops we could verify; we didn't taste every single one ourselves, but we only picked the ones that are talked about and confirmed to actually exist.
Why Kalasin plara is so well known
Kalasin has big water sources like the Lam Pao Reservoir and various rivers that supply freshwater fish for plara year-round. Good raw ingredients plus fermenting skills passed down over generations slowly turned this province into a hub for plara and bottled fish-sauce concentrate. Many of the brands you see on supermarket shelves or at som tam stalls around Thailand have their factories in Kalasin, and some makers also produce under hundreds of other brand names. Put simply, even if you've never been to Kalasin, there's a good chance you've already eaten plara from here without realizing it.

Real plara and fish-sauce brands and producers you can actually find
This isn't a ranking of which one tastes better, because plara flavor comes down entirely to personal preference. Instead, we've gathered brands and producers that can be verified as genuinely existing in Kalasin, along with where you can buy them. The prices listed are rough estimates for a standard-size bottle at market rate, and may shift with size and timing.
Mae Boonlam Fish Sauce Concentrate (Phetdam Foods)
One of the cooked fish-sauce concentrate brands people across the country recognize. The factory is in Huai Pho subdistrict, Mueang Kalasin district, and they've been making it for over 30 years, generation to generation. It's a cooked, seasoned fish-sauce concentrate you can use straight away for som tam or to mix into rice. Easy to find in big supermarkets, convenience stores and online — a good pick if you want a consistent flavor that's easy to carry home.
Mae Oi Fish Sauce Concentrate (Kaset Panrup Interfood)
A family that has made and sold plara in Kalasin for over 40 years, and produces fish-sauce concentrate for hundreds of other brands across the country. It's another original Kalasin maker that gets talked about widely, known for a rounded, savory taste you can use for som tam or as a dip. Good for anyone hunting down the old-school maker behind so many brands.
Bongnua Foods OTOP jaew bong
A jaew bong and souvenir brand from Kalasin that earned a five-star OTOP rating. They make ready-to-eat jaew bong in tubs — just open the lid and scoop it out with fresh vegetables or sticky rice. Good if you want bold, herb-fragrant jaew bong without pounding it yourself, and it's easy to carry as a souvenir since the packaging seals tighter than a bottle of plara.
Plara & pla som — Fisherman Shop @Kalasin
A shop run by the provincial fisheries office selling products from local fishers, near the Thep Suda Bridge on the way to the Lam Pao Reservoir. They have plara, jaew bong, pla som and salted fish made from freshwater fish caught in the reservoir. Good if you're already driving out to the Thep Suda Bridge or Lam Pao — pop in and buy souvenirs straight from the source.
Small-batch plara & jaew bong at the fresh market
Beyond the big brands, the fresh markets in Kalasin town have vendors who ferment their own plara and pound their own jaew bong, sold by the bag at gentle prices — homestyle flavors that locals buy regularly. The upside is fresh stock scooped into a bag in whatever amount you want, but the packaging doesn't seal as tightly as a factory bottle, so if you're carrying it far you'll want a zip bag or a box to stop spills.
Raw plara and cooked fish-sauce concentrate are different
Raw fermented plara, the kind scooped into bags, has to be boiled or cooked before you eat it. The cooked, bottled fish-sauce concentrate from the big brands has already been boiled, so you just open the lid and use it. If you're buying a souvenir for someone who doesn't cook much, go with cooked fish-sauce concentrate or ready-to-eat jaew bong — they're easier to use.
Which markets to buy plara and jaew bong at
Around Kalasin town it's not hard to find plara and jaew bong, from the everyday fresh market to lifestyle markets that bring souvenirs together. If you want big bottled brands, the supermarkets have them, but if you want fresh, small-batch stock you'll need to head into the fresh market.
Kalasin municipal night market
The main market in the Chai Sunthon area of town, with stalls of plara, jaew bong and Isan food scooped into bags — where locals buy their fresh goods.
Rong Si Market Kalasin
A lifestyle market that brings together local food, sweets and souvenirs — an easy stroll for Isan eats and things to carry home.
Lam Pao Fisherman Shop
Stop on the way to the Thep Suda Bridge and Lam Pao Reservoir for plara, pla som and jaew bong made from reservoir fish, straight from the source.
What to eat jaew bong with so it really hits
Jaew bong is a plara chili dip eaten mainly with fresh vegetables — a simple meal that every Isan household eats. Scoop the jaew bong into a bowl, set out fresh veg and sticky rice, and that alone is a filling meal. Try it like this.
- Local fresh vegetables — cucumber, yard-long beans, cabbage, holy basil, dill, mango shoots or acacia shoots, dipped in jaew bong and eaten with sticky rice.
- Blanched vegetables — if you're not into raw veg, blanch some morning glory, cabbage or yard-long beans until just done; they go well dipped in jaew bong too.
- With hot sticky rice — even one bite of jaew bong mixed into sticky rice fills you up, the quick meal of Isan.
- With grilled fish or chicken — jaew bong works as a dipping sauce in place of plain jaew, adding savory depth to grilled food.
- For seasoning som tam and larb — use cooked fish-sauce concentrate to make plara som tam or splash it into larb for extra umami.
Spicier than you'd expect
A lot of jaew bong is bolder and saltier than central-Thai chili dips. If you're not used to the taste of plara or you're not a strong spice eater, start by scooping a little at a time onto your veg, then adjust — so it doesn't catch you off guard from the first bite.
Buying it as a souvenir that travels well
- Choose a bottle or tub with a tight-sealing lid if you'll be on a long drive or flight, so it doesn't leak into your bag.
- For fresh stock scooped into a bag at the market, ask for a zip bag or put it in a box as a second layer, then tie it tight to keep the smell in and stop leaks.
- For someone who doesn't cook much, pick cooked fish-sauce concentrate or ready-to-eat jaew bong — open the lid and it's ready to use.
- Check the expiry date and FDA label, especially if you're buying a factory brand to keep for a while.
- If you're flying, liquid plara is a liquid and has to be checked under the plane — you can't carry it into the cabin — so wrap it well against spills.
